Scientific background
Independent researchYohimbine (yohimbe bark, rauwolscine)
Yohimbine is an alkaloid from the bark of the African tree Pausinystalia yohimbe. It blocks α2-adrenergic receptors, which increases noradrenaline release. Rauwolscine (alpha-yohimbine) is a closely related alkaloid.
Research evidence
Independent researchYohimbine (yohimbe bark, rauwolscine)
A small trial in professional soccer players found reduced body fat with yohimbine but no change in body mass, muscle mass or performance1. Larger, independent trials are lacking.
Evidence limitations
Independent researchThis product does not state all ingredient amounts, so the doses used in research cannot be compared with what one serving provides.
No published study has tested this specific product; the research summarised here concerns the ingredient itself.
Yohimbine (yohimbe bark, rauwolscine)
Evidence for fat loss or performance is limited to small studies. Supplement labels are often inaccurate: of 49 US yohimbine supplements tested, only 2 gave accurate information on both the quantity and the known adverse effects2.
Safety & potential risks
Independent researchYohimbine (yohimbe bark, rauwolscine)
A review of poison-centre cases found that adverse events with yohimbine products had more serious outcomes than average exposures, including rapid heart rate, anxiety, high blood pressure and agitation3. People with heart conditions, high blood pressure, anxiety disorders or taking antidepressants should not use yohimbine.
Regulatory status
Contains yohimbine HCl. Isolated yohimbine is classified as a medicinal substance in several EU member states; its legal status depends on the country of sale.
